• Facing a problem while RAC configuration on my virtual machine

  Hi all
  
  While configuration RAC 10 g on VMWare with Cent OS 4, I came across a few issues that have been resolved by rebooting (last resort)
  
  The problem is after the installation of the database by checking the cluster resources using crs_stat - t, the State shows off line for 2 resources.
  

  [oracle@rac1 bin]$ ./crs_stat -t

  The + ASM1 instance and listening on the RAC1 began not when I checked. So I started the manually.
  But when the instance is started, I got an error

  Firstly can someone tell me what "ora". SM1.asm' and «ora...» C1. LSNR"there? Why the TARGET column was also showing online?
  
  I also tried to close resources, then by restarting the services rawdevice. But after that, while trying to start (resources from crsctl) the order was simply hanging on both instances.
  
  I then didn't know what to do and just restarted both machines and then saw that everything was in place. I managed to create the database and everything works fine now.
  
  I didn't know where else to find errors. Can someone help me understand the question please?
  
  Now after setting up, I see the error in the newspaper of the ASM alerts for both nodes below.
  

  Errors in file /u01/app/oracle/admin/+ASM/bdump/+asm1_rbal_9071.trc:

  I checked the support of oracle DOC ID 1054033.1 and tried to check permissions. But I do not see the file asmadmin in $ORACLE_HOME/bin
  
  The support doc

  Solution
  
  1. Manually change the oracle binary ownership and permission:
  as root user:
  # cd $ORACLE_HOME/bin
  # chgrp asmadmin oracle
  # chmod 6751 oracle
  # ls -l oracle

  Thank you
  Abhishek.

  I'll find a virtual solution taken in charge for this and put in place on that :)

  I'll close this thread for now

  Out of curiosity, can indicate you whether it is a new application that runs on 11 GR 2? i.e. has it previously worked flawlessly on an earlier version?

  I don't know if it is the same in one of these deadlock LMD trace files but in a blocking single-instance file, there is a big warning that blocks are the result of poor application design. This is not necessarily 100% true but can often be the case. I alluded to this when I commented above on the fact that you update the cluster_id column in these tables, which is then referenced in relationship of fk - is not a drawing that I am convinced of.

  What makes the request? What does the cluster_id?

  If there are several mode TM 5 occurrences of blocking on several items, it would seem that you have multiple problems (probably the same missing fk type).

  As you can see from the info in the last trace of blocking, the declaration of the session involved is different - CCE_FULFILLMENT_ITEM_PROPS.
  Is this the same object as 0001DF1C, id of the object 122652 decimal hex?

  Can you confirm the structure of this object of the pk/fks and clues?

• How to avoid the race condition critical in the event loop?

  I'm having a problem of race in the structures of the event.  I looked through various discussions of the forum and have not been able to track down a solution.

  In the attached vi (labView2015), if you type a new number for 'X', are not press entry, and hit then the "Go" button, then the old value of 'X' is used in the case of structure.  I deduce that it is a problem of race where after clicking on the 'Go' button has undertaken a task in the structrue event and also set up something in the queue to actually update the value of the variable.  Sounds good?

  This is the simplest example I could do for this problem that has emerged in vi a lot larger and more complex.  Any help is appreciated.

  With our thanks!  Devon

  In fact, in addition to require a loop around the structure of your event, you must configure your events to the button GO to "Change the value" instead of "Mouse down".

  I should have mentioned, but I put my business in my excerpt to change value.

• Problem of Flex and Flash SWF files

  I decided to create a validation more because my previous error is much wider than expected-

  
  

  First, there are the problems with race SWF files created from the Flash IDE and loading in Flex? I have a swf swf file which works fine if I run it in the Flash IDE, the browser, the office, even in another projector file inside the Flash IDE, but as soon as I load it in Flex I start receiving errors about the flash drawing API.  These include but are not limited to: drawPath GraphicsPathWinding drawTriangles, .  I'm new to Flex so maybe I'm missing something? I understand that the swf could work anywhere else, if I loaded into Flex that would work in the same way... This also makes me hesitate using Flex, because there are some widgets that I prefer to create in the Flash IDE and then load them into Flex, but if everything is not compatible between the two so I'll just create everything in the IDE Flash.

  Which version of the Flex SDK are you using? What version of the Flash IDE are you using?

  I guess that if you are going to export your .swf to FP 9 and AS3, errors will disappear.

• Master/slave producer/consumer Feeback?

  We know that in the models of master/slave and producer/consumer can send information of the master loop or a producer to the loop of the slave or the consumer.  But what to get information of the loop of the slave/consumer back to the master/producer loop?  I think it may return some sort of output or a message saying something like "I finished my work successfully.  This can be done with local variables, but is it really a good idea?  Is there another better way?   In addition, in this case can I just use a sub - vi?    I don't know that I always get the PARALLEL treatment offerred by master/slave and producer/consumer with a sub - vi.

  You can use a notifier to send a return message.  You can use a local variable, but unless you know what you are doing, you might encounter problems with race conditions.

  Sub - VI have nothing to do with producer/consumer architectures.  You can do a p/c with or without sub - VI.  Sub - VI is a way to break the code in significant functional blocks.

• Functional Global Variable reference

  Hi all

  I want to update the value of the indicator element in primary VI, I don't want to use the global variable, due to the problem of race condition. So I create a functional global variable to control reference. It is reliable and can avoid the race condition critical?

  I have attached two Test VI.

  Thanks for your advice.

  Personally, I use user events to send data to the main VI and then he can update the indicator.  This generally works very well since most GUI screws using a Structure of the event anyway.

• Error 1: Write to text file

  Hello. I get an "error 1 write to text file" in my program.

  The error occurs occasionally and I can't understand what is causing the error. What is this error? If I ignore it and press to continue the program seems to work and it stores data. The program acquires the data and records to several files. The screenshot of the error is attached.

  Thanks for the help

  I got it. I added a variable additionl to start recording only after that the name references were initilized. It was the problem of race condition, but now I know more about the labview data flow

• Best practices using clusters to create the queue/notifier/bundles?

  I'm in a block diagram, a queue, the notifier and several instances of cluster of bundle

  that all use the same data structure.   There is a typedef of cluster for the data structure.

  Of course, each of these objects (define the queue, set notifier, bundle)

  you want to know how do you define the cluster.

  What is considered best practices?

  (1) create a dummy instance of the cluster across data structure

  definition is necessary (and hide all on the public Service)

  (2) create only one instance and son at all places, it is necessary

  But there is no stream on this thread: it's only the cluster * definition *.

  which is used, so this seems to clutter the comic.

  (3) create only one instance of the cluster control and use local variables

  everywhere else the definition of cluster is required.  It's _value_ is never

  assigned or given read-so no problem with race conditions.

  (4) another way?

  If you were to clean up someone else's code, how do you expect

  See this Treaty?

  It occurred to me during this writing that here where I

  "unbundle...... code bundle" I could wire the original beam to the

  the two "unbundle" and "bundle" - but that would be too complicated

  and the size of the comics with useless thread?

  Thank you and best regards,

  -- J.

  Hi Jeff,

  I think that this question is about "sharing" the typedef and not how share data (?)  If the cluster control is registered as a typedef (or a strict typedef) but NOT SIMPLY as a CONTROL, then when a Diagram-constant of the typedef is created, it will be updated when you update the .ctl typedef!  (and there is no FP control to hide )  Of course if the typdef is already available "close" if necessary, you will be able to use instead - save a spacer of diagram.

  See you soon.

• Convert text frame Rectangle no text

  1. is there a way to convert a block of text in text no Rectangle?

  2. Furthermore, if anyone can tell me, whenever I have manually to cover my frames of text with the rectangles, new stereotypes to rectangle on the edges of the text block existing as I was expecting, but the resulting rectangle is smaller on all sides. I suspect that this is a problem of race (track of the border), but even when I put it 0px stroke, the rectangle is still too small. How can I fix it?

  I can answer question 1, at least.

  Object > content

  From there, you can select the text, graphic or Unassigned.

  I don't really understand the second question, however. Screenshots might help.

• Function to solve any formula

  You need to write dynamic code and use bind variables. This however not a good idea, despite the use of bind variables. Many different formulas means a lot of sliders not shareable. This will be problematic - and can lead to fragmentation of memory in the Shared Pool errors and memory.

  Then there's security and risk of SQL injection. And then there are architectural decisions - PL/SQL is the right place to deal with this problem of race-Dynamics-formula ?

  Assuming that these questions are analyzed globally and PL/SQL is the environment to use, the basic approach is this:
